hope this helps.
Step-by-step explanation:
65 + (y + 9) = 180 ---------- Sum of angles on a
straight line
y + 65 + 9 = 180
y + 74 = 180
y = 180 - 74 = 106
6x + 7 = y + 9 ----------- Alternate angles
But y = 106,
6x + 7 = 106 + 9
6x = 115 - 7
x = 108/6 = 18
Answer:
Area = 142.5 square inches
Step-by-step explanation:
So your shape is kind of a little house. The bottom part is a rectangle 9 × 9.5. The area of the rectangle is
Area = length×width
= 9 × 9.5
= 85.5
The "roof" of the little house is a triangle. The area of a triangle is 1/2×base×height
Now, the base of the "roof" is the same as the floor of the house, 9.5 inches.
The height of the whole thing is 21 inches. If we take away the rectangle's wall-height, we'll get the height of the "roof".
Roof height= 21 - 9
= 12 inches
Area_roof
=1/2 × base × height
=1/2 × 9.5 × 12
= 57 square inches
Total area is bottom plus roof (the rectangle and the triangle)
Total Area
= 85.5 + 57
= 142.5 sq in
Answer:
its b just did quiz
Step-by-step explanation:
Your specific question was how many " hours " did he work this week so,
Monday: 7 whole hours
Tuesday: 5 whole hours
Wednesday: 6 whole hours
Thurs.-Fri.: Was off.
So that makes 7+5+6=18 hours.
The 30 minutes from Monday & 20 minutes from Tuesday doesn't equal one whole hour so it doesn't count.
